APPARATUS FOR HEATING FEED-WATER.

SPECIFICATION forming part of Letters Patent No. 367,750, dated August2, 1887. Application filed March 22, 1887. Serial No. 231,950. (Nomodel.) Patented in England February 19, I857, No. 2,625.

To all whom it may concern.-

Be it known that I, ROBERT ROBSON LITTLE, timber agent, a subject of theQueen of Great Britain and Ireland, and residing at 3 Meldon Terrace,\Vestoe, South Shields, county of Durham, England, have invented certainnew and useful Improvements in or Connected with Apparatus for HeatingFeed-\Vater for Steam Boilers, or for other purposes, (for which I andJohn Hall have applied for a patent in Great Britain on the 19th ofFebruary, 1887, No. 2,625,) of \vhieh'the following isa specification.

This invention has for its object to provide apparatus by means of whichthe water is withdrawn from the heater at or toward the surface of thewater, in the latter case the distance from the surface at which thesupply is drawn being predetermined and adjustable, if desired. Theoutlet for the hot water is provided with a hinged or swivelingconnection furnished with a float or buoy, by which the inletto thisconnection is carried up as the level of the water in the heater rises,and al lowed to fall as the level of the water falls, so that the inletto the continuation is constantly .maintained at the surface of theWater or at any desired distance beneath the surface.

The float or buoy may be connected to the continuation by a chain orother means, by which the distance below the surface of the water of theinlet to the continuation may be adjusted. The water only reaches theoutlet from the heater by passing through the inlet of the continuationand therethrough to the outlet to which the said connection is hinged orswiveled. V

I will describe, with reference to the accompanying drawings, manners inwhich the invention may be carried out in practice. I do not, however,limit myself to the precise details shown.

Figure 1 is a vertical section and Fig. 2 a

sectional plan illustrating the arrangement 1 without provision foradjustment of the inlet to the connection relatively to the surface ofthe water, while Fig. 3 shows a section of an arrangement wherein sucha. provision is made, and Fig. 4 shows a modification thereof.

Referring to Figs. 1 and 2, A is the vessel in which the feed-water isheated by steam entering the pipe B.

O is the pipe supplying cold water, and D is the outlet-pipe leading tothe boiler or other place where the hot water is to be utilized.

The outlet-pipe is angled at cl, and in it is inserted the angled end orelbow of the pipe E, forming the hereinbefore described continuation.The pipe E communicates with the pipe D at the joint formed by theangled ends (I and e, as shown in Fig. 1. end of the pipe E is fixed theball-fl0at F, and near the upper end of the lower side of the pipe E areopenings 0. The float F maintains these openings near the surface of thewater as the height of the water in the heatervaries, the pipe E turningupon its jointing with the pipe D, whereby the water is drawn 011' whereit is hottest, or at the heat required, the said.

water passing in through the openings 0, along To the outer the pipe E,and through the joint (1 0 out by the pipe D to the boiler or otherplace. Fig. 3 shows an arrangement whereby the distance at which theinlets c are maintained below the surface of the water can be adjusted,the pipe E being connected to the buoy F by means of a chain, j, whichcan be adjusted so that the distance of the top of the pipe E from thebottom of the float can be altered in accordance with the depth belowthe surface at which it is desired to draw off the water.

Fig. 4 shows a modification wherein the chain is replaced by a stem, fhinged to the pipe E and passing through the buoy F, and connectedthereto by a loop or eye, a", in which engages a pin or screw, 0*, whichenters one or other of the holesf, in accordance with the depth belowthe surface at which it is desired to draw off the water.

The inlets e are shown as being on the under side of the pipe E, so asto prevent foreign o matter passing thereth rough.

I claim In water-heaters, a hinged, jointed, or swiveling connectionwith the passage for water to the outlet, in combination with a float orbuoy attached to and adjustable relatively to the said 5 hingedconnection, in order to vary the distance below the surface at which theinlet end of said connection is maintained, as hereinbefore set forth.

In testimony whereofI have signed my name to this specification in thepresence of two subto scribing witnesses.
